AUsTIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Brake Mechanism for Pivoted Oar-Trucks, of which the following is a specification.

The object of my invention is to so construct the brake operating mechanism of a pivoted car truck that the car truck is free to swing without affecting the brake mechans eave. ism. This object I attain in the following Thus it will be seen that the truck can manner, reference being had to the accomswing on its pivot without in To al whom it may concern: I

igure 1, is a plan view of suflicient of a ch pivoted railway truck to illustrate my invention; Fig. 2, is a longitudinal sectional view of the truck; and Fig. 3, is a sectional view showing the car body transom.

In the drawings I have omitted the details of construction that do not relate'particular to the brake mechanism in order to avoid confusion.

are the axles and b b the wheels.

A is the truck transom having the usual bolster and springs.

D is the car body transom, the truck being pivoted to the transom by a king bolt d.
